To provide a vehicle detector, a vehicle detection method and a program which are installable in a reduced space, and with which it is possible to reduce misdetection.SOLUTION: The vehicle detector comprises: a first distance measuring sensor for irradiating light in an irradiation cycle and thereby detecting a first distance that is the distance on a vehicle road to a first position that is a first end part of a vehicle in the travel direction of the vehicle; a second distance measuring sensor for irradiating light in the irradiation cycle and thereby detecting a second distance that is the distance from the first position to a second position that is a second end part of the vehicle on the upstream or downstream side of the travel direction of the vehicle; and a vehicle detection unit for determining, on the basis of the first and second distances, that the vehicle passing down the vehicle road is detected, when the first and second distances are less than or equal to a distance threshold a count threshold or more in succession. The first and second distance measuring sensors are installed so that the radiation direction of the first distance measuring sensor and the radiation direction of the second distance measuring sensor form a prescribed angle, and the vehicle detection unit sets a count threshold in the irradiation cycle.SELECTED DRAWING: Figure 2

    【課題】省スペースに設置でき、且つ誤検知を低減できる車両検出装置、車両検出方法、及びプログラムを提供すること。【解決手段】車両検出装置は、車路において車両走行方向の車両の第1端部である第1位置との間の距離である第1距離を、照射周期で光を照射することで検出する第1測距センサと、第1位置から車両走行方向上流側又は下流側の車両の第2端部である第2位置との間の距離である第2距離を、照射周期で光を照射することで検出する第2測距センサと、第1距離と、第2距離とに基づいて、回数閾値以上連続して、第1距離と第2距離とが距離閾値以下となる場合に、車路を通過する車両を検出したと判定する車両検出部とを備え、第1測距センサと、第2測距センサとが、第1測距センサの放射方向と第2測距センサの放射方向とが所定の角度をなすように設置され、車両検出部は、照射周期で、回数閾値を設定する。【選択図】図2
